ZHC618F-1000W/C integrated FM radio transmitter Introduction: The transmitter adopts a simple design concept, and installs the exciter and power amplifier, output filter and switching power supply of 1KW FM stereo transmitter in a 3U high 19-inch standard chassis, which reduces the parts between ordinary transmitters. The connection cable is more reliable and easier to operate. Using the latest DSP + DDS full digital technology stereo frequency exciter, the machine's technical indicators are unparalleled, reaching close to CD sound quality auditory effects. The large size radiator and 3 German original high speed, long life fans ensure that the transmitter works in a reliable low temperature state. Adopt Taiwan's original Mingwei wide range switching power supply. High reliability, high performance, easy operation and low price. Features: 1.Simple design, integrated structure, high reliability, easy operation 2. Full-process digital processing (DSP+DDS) to achieve a perfect auditory effect close to CD sound quality 3. Analog audio and digital audio (AES/EBU) can be input simultaneously, digital audio is preferred 4. With TCP / IP, SMS cat, RS232 communication interface, can use computer management and monitoring 5. Perfect over-current, over-voltage, over-temperature, over-power, standing wave ratio alarm and protection function 6. Large-screen LCD displays operating parameters in real time 7. High quality stainless steel, 3U, 19 inch standard chassis Technical Parameters: RF frequency range: 87MHz~108MHz Stepping 10kHz (other frequencies can be customized) Output power: 0~1000W continuously adjustable Output impedance: 50Ω RF output connector: 7/8' flange or L27K or 7/16' Internal residual wave: < -70dB Higher harmonics: < -60dB Parasitic amplitude modulation : < -50dB Carrier frequency tolerance: ±200Hz Analog audio input: -12dBm ~ +8dBm Audio level gain: -15dB ~ +15dB step 0.1dB Analog audio input impedance: 600Ω balance AES/EBU input impedance: 110Ω balance AES/EBU input level: 0.2~10Vpp AES/EBU sampling rate: 30kHz~96kHz SCA input : Unbalanced (optional) BNC type connector Audio pre-emphasis: 0μs, 50μs, 75μs Frequency response : ±0.1dB 30Hz～15000Hz Left and right channel level difference: <0.1dB (100% modulation) Stereo resolution: ≥50dB 30Hz～15000Hz Stereo signal to noise ratio: ≥70dB 1KHz, 100% modulation Distortion : <0.1% 30Hz～15000Hz Heat dissipation method: forced convection Temperature range: -10 ° C ~ +45 ° C Relative humidity: <95% Altitude : <4500m Power consumption : 1600VA Dimensions : 605mm × 483mm × 133mm Weight : 36KG
